CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 278,334, dated `May 29, 1883. Application tiled February 23, 1883. (No model.)

To all whom tt mag/concern.-

Be it known that I, HALE E. HAWK, a citizen of the United States, residing at Kansas City, in the county of Jackson `and State of Missouri, have invented certain new and use ful Improvements in Car-Couplings; and I do .hereby declare that theV following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention has for its object a novel combination, and arrangement of self-coupling devices for adaptation to the draw-head of a car when providedl with the mechanism as described and claimed in-my application of J anuary 15, 1883, and also in `a novel combination and arrangement oi' the shackle without necessitating` a change in the construction of it, which will 'self-act upon the coupling devices upon the car to elevate the bolt and couple its relative parts; and it consists, fiirst, in the mechanisml upon the draw-head which operates to elevate the bolt," and permits, also, an in- Y dependent movement in the releasing of the coupling devices; second, ,in` the novel arrangement of the shackle for elevating the coupling-bolt.

In the drawings, Figure 1 is a vertical sectional view of the draw-head and coupling mechanism with the shackle in position to en;

.ter the draw-head. Fig. 2 is a side elevation of the draw-head and coupling devices thereon. Fig. 3 is a front view of the draw-head .and coupling mechanism. Fig. 4. is a top view ot' shackle and self-coupling devices thereon. Fig. 5 is an end elevation of the same.

A represents a draw-head of a car. B isla' couplingbolt. C is a lifting-bar of a suitable is a wrist upon said arm. K is an angle-iron attached to guide-box Gr by nuts dl el. P is a 5o tripping-leveren rock-shaft E. M is a common and well-known shackle. O is a self-adjusting arm attached to shackle `M by a verti-l cal bar, N, and having cross-bar o.

In the construction of my invention I arrange in a transverse relation to and beneath the draw-head in guide-box G a rock-shaft, E, and secure said shaft from lateral play by suitable bolt-heads or other retaining devices. A lifting-arm, F, is then arranged upon the rockshaft E, between the lifting-bolts D D and the guide-box G. Upon the lower end ot' the bolts D D, I arrange an arm, H, in the same vertical relation thereto, and adjust said arm upon the bolts at any varying height by the screw h, At right angles to and at the upper end ot' the adjustable arm H, I attacha wrist, g, in line with the lifting-arm F on the rock-shaft E, by which arm the adjustable arm H and liftingboltsD D are elevated. Upon the rock-shaft E, and midway of the same., I arrange a trippinglever, P, of sufficient length to meet the crossbolt o of the self-adjusting arm of the shackle. In advance of the shackle M, and connecting the two opposite portions of the self-adjusting arm. O together, is the cross bolt or bar o, which meets the depending tripping-lever P on rock-shaft E, and communicates a partial rotation to said shaft and a rear movement of the liftingarm F against the wrist g ot' the vertical and adjustable arm H, attached to the lifting-bolts, by which operation the said liftin g-bolts are raised, and also the coupling-bolt, from theirordinary position when. coupled. The cross bolt or bar o, in its contact.with the tripping-lever P, acts to throw the same in rear until past its radiate lengt-h,- when it instantly falls to a vertical position, releasing the support tothe adjustable arm H and permitting the fall ot' the coupling-bolt, the posiy tion of the shackleat the moment of the releasing ofthe tripping-lever being within the draw-head and past the coupling-bolt, rwhereby the shackle is retained. v In the adaptation of my invention, particularly to freight-cars, the releasing of the shackle, either from accident or by lifting devices upon the car, permits the self-adjusting arm to be withdrawn, the lifting-arms being arranged to act independently of the liftingbolts, whereby the tripping-leverswings outwardly on the cross-bolt of the self-adjusting arm until past its length, When said lever falls to its usual or vertical position.

Having fully described my invention, what I now claim, and desire to secure by Letters Patent, is-

1. In combination with the draw-head of av car provided exteriorly with a suitable guidebox arranged beneath and extending beyondi shaft, substantially as described.

2. In combination with the draw-head of a car provided exteriorly with a suitable guidebox arranged beneath and extending beyond the opposite sides of said draw-head, andoppositelyLarranged lifting-bolts in said guides, which are connected with the coupling-bolt and provided with an adjustable arm and Wrist., a rotary shaft arranged transversely Within said guide-box and beneath said draw-head, and provided with suitable extensions vto engage With the Wrist upon the,adjustable arm of said lifting-bolts, as described.

3. In combination with a self-adjusting arm attached by a suitable bar to and in a parallel relationbeneath a shackle7 and provided with suitablyinclined ends, a bolt or bar arranged upon and in a transverse relation to said arm,

for the purpose specified.
